Low Mid temperature Alloy Solder

A low temperature solder of bismuth, indium, cadmium in the formation of solder in the solder alloy, mainly for microelectronic sensor assembly of parts with low heat resistance, good wettability and solderability, solder full, uniform welding excellent results, without requiring high temperatures and pressures may be used to seal solder metal welding.

Like many other solder materials, the
low-mid temperature alloy solder is used for soldering aluminum metal and
alloys, and to some lesser extent steel and zinc. It is a lead free solder
whose principal element is SN. Its mechanical soldering is similar to a low
temperature brazing operation, in that the mechanical characteristics of the
joint are reasonably good. Besides, this alloy solder can be used for
structural repairs of those materials.

Features

1. Low-mid temperature alloy solder has
good brazing effect and great fluidity.

2. The mechanical performance is perfect.

3. After welding, this lead free solder
has high reliability and fine thermal fatigue property.

4. The low-mid temperature alloy solder can
be compatible with all copper-based radiator solder alloys and lead solders.

5. With this solder, repairs are stronger
than original joint and have a higher melting point than original joint. It is excellent
for radiator repair.

Type

Low-mid temperature alloy solder has two
subclasses as follows.

(1)
Sn91Zn9 Alloy Solder Bar (Tin Zinc Alloy Solder Bar)

(2) Sn89ZnBi3 Solder Bar (Tin Zinc Bismuth Alloy
Solder Bar)

Different alloys have
different solidus and liquidus melting points. Please refer to the following
pictures.
